A cube has a lateral area of 676 square feet.<br> What is the side length of the cube?
sp2606 [1]

Answer:

13 ft.

Step-by-step explanation:

Lateral Surface area of a cube is the area of 4 sides, front side, back side, left side face and right side face.

It can be seen seen from the attached figure as well.

Each face in a cube is a square. And each side in the cube is equal.

So, Lateral surface area is nothing but 4 \times area of a square.

And we know that area of a square = side^{2}.

Hence, Lateral surface area = 4 \times side^{2}

As per question:

4 \times side^{2} = 676

side^2 = 169 \\\Rightarrow side = 13

Hence, side length of cube = 13 feet.
